2,051,979 DIvmmG STRIP Samuel C. Awbrey, Kansas City, Mo. Application February 27, 1935, serial No. 8,477 12 claims. (o1. eti-17)' This invention relates to a dividing strip used in producing patterns in floors, which are formed of a plastic material and then permitted to harden. VOne of the most common of this type of iioor is the terrazzo.

The principal object of this invention is the provision of a dividing strip having tongues stamped therefrom, and which are formed to extend outwardly from the general plane of the strip with their free ends extending into the slots formed in the strip by the removal of the tongues.

tAnother object of the present invention is the provision of a dividing strip having tongues integral therewith, said tongues being formed and positioned with their" freeends positioned transversely in the slots formed by the punching of Athe tongues from the strip and means for preventing movement of the tongue transversely of the strip.

A further object is the provision of a dividing strip having a tongue stamped therefrom and positioned with its free end extending transversely through the slot formed through the strip.

Other objects are economy and simplicity of construction and ease and efficiency' of operation.

With these and other objects in view which will appear duringthe course of the specification, reference will now be had to the drawing, wherem.

Throughout the several views like reference numerals designate similar parts and the numeral indicates'a strip or' bar' of metal, hav- 15 ing an uninterrupted upper edge 22. While this member 2li-'is shown'as a strip of flat material having its `opposite edges parallel, however, it is apparent that it might be made from a bar of any-other suitable form. For instance, it might be possible to make the uninterrupted upper O.

edge thicker than the major portion of the strip;

also, the strip might be produced by Vsecuring together strips of material of rdifferent widths.`

The form of `dividing strip as shown in Figs. 1

2, 3 and ,4 is provided'with groups of longitudinal-1 2'5- ly spaced, loop-formed bonding projections 24. Each group consists of two longitudinally disposed loop members'formed by stamping tongues from the bodyof the strip and then bending 30 the tongue outwardly beyond the plane `ofthe strip with thefree end 28 thereof projected into slotY 3,0, which is formed in the strip by` the removal of said tongue.,

-Itwill be observedV that the tongues of ,each 35 group are oppositely disposedand'that an opening 32 is formed, through which fastening or vanchoring means might be projected to'facilitate properpositioning of the strip in certain types of" installation. This formA of the dividing strip 40 is 4provided with one face ,'341whichis free from projections, while the opposite side k36 thereof has the loop-formed binding projections. When laying a floor surface of this type in which itis necessary to use abutting anglev strips asshown in-Fig. 4,it is apparent that the strip 38jmay be positioned at anypoint along the one side of thev continuous strip 40. r

Referring to Fig. 3, in which a cross sectional View of the strip in operative position in a oor construction is shown, 42 designates the foundation bed rof the floor, while 44 is an intermediate bed of cement, into which the lower portion Aof the 'dividing strip is inserted while the same is wet. It will be observed that .thetongues are 55 stamped from the lower portion of the strip with their upper edges positioned substantially on the center line, thereby serving as a depth gauge to determine the degree of insertion. Furthermore, these loops, together with the slots, serve as means for binding the strip in the intermediate or under bed of the floor. After the under bed 44 has hardened, the terrazzo or wearing surface 46 is added to a depth such that the upper uninterrupted edge 22 of the strip is flush therewith. This upper surface is then ground and polished to produce a wearing surface with the edges of the strips exposed to form any desired pattern.

In Fig. 5 it will be observed that the free ends of the tongues of each group are in adjacent relation, while in the modified form shown in Fig. 6 the free ends of these tongues are projected in like directions. The groups of bonding projections 158 as shown in Fig. 7 are alternately projected from opposite sides of the strip to produce a uniformly balanced structure.

The principal diierence between the modified form shown in Figs. 8 and 9 is the provision of a formed tongue 50 which extends entirely through the slot 52 to produce a bonding projection at both sides of the strip. The tongue 54 which is shown in Fig. 10 is provided with a shoulder 56 at its free end which, when the tongue is in the operative position, serves to prevent outward movement of the tongue from the slot 58. When the tongue is so formed, slot 5B is offset asat 6U.

In the modified form shown in Figs. 11 and 12, the tongue is provided with two downwardly projecting portions 62 and 64 which are adapted to be positioned at opposite sides of the strip to preclude any transverse movement of the free end of the tongue when the same is in the operative position.

Referring to Fig. 13, tongue 66 is formed with a downwardly extending portion 68 adjacent its free end which is adapted to be inserted in slot 10 formed in the lower marginal edge of slot 'l2 to prevent movement of the free end of the tongue in a direction longitudinally of the strip. While the tongue securing means shown in Figs. 10, 11, 12 and 13 have been limited to but one edge of the tongue, however, it is apparent that a like securing means might be provided for the top edge without departing from the spirit of the invention. It will be observed that in all of the forms shown that the free end of the tongue is inserted into or through the slot, thereby producing a very rigid and eflicient bonding projection without the necessity of drawing the metal, thus making it possible to produce a very convenient and eflicient binding strip of substantially any material that will permit of slight bending.

The tongues shown are all in longitudinal, parallel relation to the strip, however, they might be positioned at any desired angle relative to the strip, also the opening or slot into which the free end of the tongue is projected might be one other than that formed by the stamping of the tongue.

What I claim is:

1. A dividing strip for terrazzo floors or the like having a tongue carried at its one end by the strip and having its free end projected into a slot formed in said strip. Y

2. A dividing strip for terrazzo floors and the like having integral tongues punched therefrom to form slots in the strip, said tongues being formed and positioned with their free ends extending into their respective slots intermediate the ends thereof.
